土壤多环芳烃及其化学氧化修复技术研究进展

多环芳烃作为广泛分布于各类环境介质的持久性有机污染物,在全球环境治理技术研发及应用中备受关注。土壤作为重要的环境介质,在近年来不断发展演变的工业化进程中已成为重要的多环芳烃汇,且储存了环境中超过90%的多环芳烃。从土壤多环芳烃化学氧化技术的角度,阐述了原位/异位氧化修复技术、高锰酸钾、臭氧、芬顿及过硫酸盐氧化技术在近年来的研究进展并进行了展望。

Research Progress on Soil Polycyclic Aromatic Hydrocarbons and Their Chemical Oxidation Repair Techniques

As a persistent organic pollutant widely distributed in various environmental media, polycyclic aromatic hydrocarbons have attracted much attention in the development and application of global environmental management technologies. As an important environmental medium, soil has become an important polycyclic aromatic hydrocarbon sink in the evolving industrialization process in recent years, and it stores more than 90% of polycyclic aromatic hydrocarbons in the environment. In this paper, from the perspective of chemical oxidation technology of polycyclic aromatic hydrocarbons in soil, the research progress of in situ/ecological oxidation repair technology, potassium permanganate, ozone, Fenton and persulfate oxidation technology in recent years is discussed and prospected.
